Description

Technical Field

[0001] The present invention relates to the field of red mud processing, in particular to a negative pressure water quenching furnace for red mud processing. Background Art

[0002] Red mud is an industrial waste residue generated during the production of alumina and is named for its red appearance. The direct dumping of red mud will cause environmental pollution. At present, red mud is mainly treated by water quenching to realize the reuse of its internal components.

[0003] Red mud water quenching is to directly contact high-temperature red mud with water, so that the red mud is rapidly cooled in a very short time. This process utilizes the characteristics of water having a large specific heat capacity and a high heat of vaporization, which can quickly absorb the heat of the red mud and achieve the rapid cooling treatment of the red mud. After the water quenching treatment, the physical properties of the red mud change, the structure becomes loose and porous, and the specific surface area increases. This is beneficial to the contact and reaction of various chemical reagents with the useful components in the red mud during the subsequent comprehensive utilization of the red mud, and improves the extraction efficiency of valuable components. For example, when extracting metal elements such as iron and aluminum in red mud, the water-quenched red mud is more easily leached by acid or alkali solutions, thereby increasing the metal recovery rate.

[0004] However, because the traditional water quenching furnace is connected to the outside atmosphere, the red mud is easily oxidized and deteriorated, reducing the subsequent utilization value; and the water quenching efficiency is low, unable to adapt to the industrial-scale red mud treatment requirements, with high energy consumption, complex equipment, and maintenance costs that are prohibitive. At the same time, during water quenching, after filtering the red mud suspension, it is impossible to conveniently clean the water quenching furnace to remove the unqualified red mud slag filtered therein. Therefore, a negative pressure water quenching furnace for red mud processing is proposed. Summary of the Invention

[0009] Preferably, hinge seats are installed on both the upper and lower sides of the sliding frame. The spring hinge is installed inside the hinge seat. The hinge seat is rotatably connected to the rotating block through the spring hinge. The rotating blocks on both the upper and lower sides rotate away from each other and are limited by the inner wall of the hinge seat parallel to the axial direction of the water quenching furnace.

[0010] Preferably, a limiting guide rod is connected to the disc rack along the axial direction. A sliding ring is slidably sleeved outside the limiting guide rod. A first spring sleeved outside the limiting guide rod is connected between the sliding ring and the limiting guide rod. Each cleaning collar sleeve is arrayedly connected to the outside of the sliding ring. The top plate cooperates with and abuts against the sliding ring.

[0011] Preferably, a rubber ring is embedded in the inner wall of the cleaning collar sleeve. The rubber ring fits and slides on the outside of the stirring rod.

[0012] Preferably, the driving component includes a telescopic member, a connecting seat, and a rotating plate.

[0016] The beneficial effects of the present invention are: 1. The technical solution of the present invention is to put the high-temperature red mud into the water quenching furnace through the feed pipe, and then the water quenching furnace can be vacuumed through the vacuum module to achieve water quenching in a vacuum environment, avoid red mud oxidation, and improve output quality. At the same time, the driving assembly can drive the slide frames on both sides to slide close to each other. At this time, the rotating block has no resistance from the top plate and rotates to a vertical state, so that each stirring rod rotates and stirs parallel to the axial direction of the water quenching furnace. When the stirring rod is parallel to the axial direction of the water quenching furnace, the red mud added from the feed pipe can be well dispersed, and the sliding frames on both sides can be driven away from each other, so that the rotating block is in conflict with the top plate, and each stirring rod is driven to rotate and stir vertically to the axial direction of the water quenching furnace, so that the stirring direction can be flexibly adjusted, and the water quenching efficiency is effectively improved; 2. The technical solution of the present invention can drive the limit plate to pass through the slideway through the conflict between the conflict seat and the vertical plate in the stabilizing assembly, and conflict with the side of the rotating block parallel to the axial direction of the water quenching furnace, thereby ensuring the stability of the rotating block in the vertical state, and at the same time improving the stability of each stirring rod in the vertical state. When the rotating block and the stirring rod are perpendicular to the axial direction of the water quenching furnace, that is, when the top plate and the rotating block are fully conflicted, the top plate can conflict with the side of the rotating block away from the hinge seat, and the rotating block itself can conflict with the hinge seat, which can also ensure its stable operation in the horizontal state; 3. Through the mutual approach of the two sliding frames on both sides, the technical solution of the present invention can drive the upper inclined block and the lower inclined block in the linkage assembly to abut against each other, thereby pushing the mounting frame downward, so that the filter screen and the annular platform are sleeved in the discharge pipe orifice, and effective filtration is carried out during feeding, ensuring that the red mud suspension will not seep out unfiltered from the edge of the filter screen. At the same time, when the feeding is ended and there is red mud residue in the water quenching furnace, the two sliding frames on both sides are driven to move away from each other, canceling the abutment between the upper inclined block, the lower inclined block and the mounting frame. At this time, the filter screen and the annular platform are moved out of the discharge pipe orifice, which is convenient for flushing the water quenching furnace and directly discharging through the discharge pipe orifice to ensure the stable progress of the next water quenching.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] like Figure 1-11 As shown, the present invention discloses a negative pressure water quenching furnace for red mud processing, comprising a support 1, a water quenching furnace 2 is installed on the support 1, a feed pipe opening 3 and a discharge pipe opening 5 are respectively arranged at the upper and lower ends of the water quenching furnace 2, a vacuum module 9 and a heating module 11 are installed on the water quenching furnace 2, both inner walls of the water quenching furnace 2 are connected with slides 14, and each slide 14 is slidably connected with a slide frame 15, the upper and lower sides of the slide frame 15 are rotatably connected with a rotating block 19 through a spring hinge, a motor 20 is embedded at the end of the rotating block 19, and a disc rack 21 is connected to the output end of the motor 20, and a stirring rod 22 is connected to the disc rack 21 in an array, and the inner wall of the water quenching furnace 2 is also connected to a top plate 28 that contacts the rotating block 19; The vacuum module 9 and the heating module 11 are both existing vacuum equipment and heating equipment, which can realize water quenching of red mud under negative pressure conditions, prevent the red mud from being oxidized, improve the quality of the red mud, and lay a solid foundation for subsequent high-value utilization; A driving component is arranged inside the water quenching furnace 2. The driving component is used to drive the sliding frame 15 to slide horizontally inside the water quenching furnace 2. A plurality of cleaning collar rings 26 sleeved outside each stirring rod 22 are slidably connected to the tray rack 21 along the axial direction. The top plate 28 also cooperates and abuts against the cleaning collar rings 26. A stabilizing component is arranged on the sliding frame 15. The stabilizing component is used to stabilize the rotating block 19 in the vertical state. A filter screen 42 sleeved inside the discharge pipe orifice 5 is slidably arranged at the bottom of the water quenching furnace 2. A linkage component is arranged on the filter screen 42. The linkage component is used to drive the filter screen 42 to fit with the discharge pipe orifice 5 when the sliding frame 15 slides.

[0021] A plurality of equipment bins 10 are arranged in an array on the inner wall of the water quenching furnace 2. Two sliding frames 14 and the top plate 28 are symmetrically connected to the inner walls on both sides of the equipment bin 10 along the radial direction. Two heating modules 11 are symmetrically installed on the inner walls on both sides of the other two equipment bins 10 along the radial direction. The arrangement of the equipment bins 10 is beneficial to accommodating the heating modules 11 and the structures on the sliding frame 15 therein, thereby increasing the available space capacity inside the water quenching furnace 2.

[0022] The feed pipe orifice 3 extends into the water quenching furnace 2, and a spraying head 4 is installed at the extended end. A spray pipe rack 7 is also installed on the upper inner wall of the water quenching furnace 2. A spray pipe rack 7 is arranged on one side of each spraying head 4. A plurality of nozzles 8 are equally spaced and installed on the side of the spray pipe rack 7 close to the spraying head 4. A battery valve 6 is installed at the lower end of the discharge pipe orifice 5. In this way, the red mud added through the feed pipe orifice 3 can be sprayed through the spraying head 4 and then be fully mixed with the water sprayed from the nozzles 8 on the spray pipe rack 7 on one side.

[0023] Hinge seats 18 are installed on both the upper and lower sides of the sliding frame 15. Spring hinges are installed inside the hinge seats 18. The hinge seats 18 are rotatably connected to the rotating blocks 19 through the spring hinges. The rotating blocks 19 on the upper and lower sides rotate away from each other and are limited by the inner wall of the hinge seats 18 parallel to the axis of the water quenching furnace 2. That is, the rotating blocks 19 have a force to rotate to one side under the action of the spring hinges. The direction of this force is to drive the upper and lower rotating blocks 19 to rotate to a state parallel to the axis of the water quenching furnace 2. At this time, the rotating blocks 19 will also abut against and be limited by the side of the hinge seats 18 away from the axis of the water quenching furnace 2.

[0024] The disk rack 21 is axially connected with a limiting guide rod 23. A sliding ring 24 is sleeved on the outer side of the limiting guide rod 23. A first spring 25 sleeved on the outer side of the limiting guide rod 23 is connected between the sliding ring 24 and the limiting guide rod 23. Each cleaning collar 26 is array - connected to the outer side of the sliding ring 24. The top plate 28 cooperates with and abuts against the sliding ring 24, so that under the action of the first spring 25, the sliding ring 24 can be driven to abut against the disk rack 21. When the rotating block 19 abuts against the top plate 28 and drives the rotating block 19 to rotate to a state perpendicular to the axial direction of the water quenching furnace 2, at this time, if the driving assembly continues to drive the sliding frames 15 on both sides to move away from each other, the top plate 28 will gradually abut against the sliding ring 24, thereby driving the sliding ring 24 to slide horizontally along the limiting guide rod 23 and compressing the first spring 25. During this process, each cleaning collar 26 connected to the outer side of the sliding ring 24 will slide along the outer side surface of the stirring rod 22, realizing the scraping and cleaning of the surface of the stirring rod 22, ensuring that less red mud and related substances adhere to the surface of the stirring rod 22, and enabling the stirring rod 22 to always have a high stirring efficiency.

[0025] A rubber ring 27 is also embedded in the inner wall of the cleaning collar 26. The rubber ring 27 fits and slides on the outer side of the stirring rod 22, further improving the cleaning effect of the cleaning collar 26 on the surface of the stirring rod 22 when sliding on the surface of the stirring rod 22. Embodiment

[0026] As Figure 1-11 shown, the present invention discloses a negative - pressure water quenching furnace for red mud processing. Compared with Embodiment 1, the structure of the driving assembly is disclosed in this embodiment.

[0027] The driving assembly includes a telescopic member 12, a connecting seat 13, and a rotating plate 17. The telescopic member 12 is installed on the upper inner wall of the water quenching furnace 2. The connecting seat 13 is installed at the output end on the lower side of the telescopic member 12. Rotating plates 17 are rotatably connected between the connecting seat 13 and the symmetric sliding frames 15 on both sides.

[0028] When the telescopic member 12 extends, it can drive the sliding frames 15 on both sides to slide away from each other. When the telescopic member 12 contracts, it can drive the sliding frames 15 on both sides to slide closer to each other. Embodiment

[0029] As Figure 1-11 shown, the present invention discloses a negative - pressure water quenching furnace for red mud processing. Compared with Embodiment 2, the structure of the stabilizing assembly is disclosed in this embodiment.

[0030] The stabilizing assembly includes a vertical plate 16, a slide opening 29, a slide plate 31, and a limit plate 33. The vertical plate 16 is connected to the slide frame 14. The slide opening 29 is opened on the upper and lower sides of the slide frame 15. The upper and lower sides of the slide frame 15 are connected with a slide rod 30. The slide plate 31 is symmetrically arranged on the upper and lower sides, and is slidably sleeved on the outer side of the slide rod 30 on the upper and lower sides. A spring 2 32 sleeved on the outer side of the slide rod 30 is connected between the slide plate 31 and the slide frame 15. The limit plate 33 is connected to the upper and lower slide plates 31 on one side away from each other, and slides through the slide opening 29 on each side and the corresponding rotating block 19 for vertical limitation. The slide plates 31 on the upper and lower sides are rotatably connected with a rotating rod 34, and the other ends of the two rotating rods 34 are rotatably connected with a resistance seat 35 that cooperates with the vertical plate 16.

[0031] When the rotating block 19 contacts the top plate 28 and is in a vertical state perpendicular to the axial direction of the water quenching furnace 2, the top plate 28 can contact the side of the rotating block 19 away from the hinge seat 18, while the other side of the rotating block 19 can contact the inner wall of the hinge seat 18 to maintain stability; When the friction between the rotating block 19 and the top plate 28 is eliminated, that is, the sliding frames 15 on both sides slide close to each other, the rotating block 19 is in a vertical state under the rotation of the spring hinge, that is, the rotating block 19 can be in friction with the inner wall of the hinge seat 18 on the axial side away from the water quenching furnace 2, but the other side has no limit and is easy to shake when driving the stirring rod 22 to rotate. At this time, the sliding frames 15 on both sides can continue to be driven close to each other until the friction seat 35 conflicts with the vertical plates 16 on each side, and drives the rotating rod 34 to rotate, so that the slide plates 31 on the upper and lower sides drive the limit plates 33 on the upper and lower sides to move away from each other, until the limit plates 33 slide through the slideway opening 29 and fit the limit on the side of the rotating block 19 close to the axial side of the water quenching furnace 2. At this time, the stability of the rotating block 19 in the vertical state can be guaranteed, thereby improving the stability of the overall operation of the device. Example

[0032] like Figure 1-11 As shown, the present invention discloses a negative pressure water quenching furnace for red mud processing. Compared with the third embodiment, this embodiment discloses the structure of a linkage component.

[0033] The linkage assembly includes a connecting frame 36, an upper inclined block 37, a mounting frame 39, and a lower inclined block 44. The connecting frame 36 is provided in two pieces and is symmetrically connected to both sides of the sliding frame 15. The upper inclined block 37 is connected to the lower end of the connecting frame 36, the mounting frame 39 is connected to the filter screen 42, and the lower inclined block 44 is connected to the mounting frame 39. The upper inclined block 37 fits and slides against the lower inclined block 44 and the mounting frame 39.

[0034] The lower inner wall array of the water quenching furnace 2 is connected to a slide bar 2 38, a mounting frame 39 is slidably mounted on the outer side of the slide bar 2 38, a spring 3 40 mounted on the outer side of the slide bar 2 38 is connected between the mounting frame 39 and the lower inner wall of the water quenching furnace 2, a connecting rod 41 is connected to the lower end of the mounting frame 39, and is connected to the upper end of a filter screen 42 through the connecting rod 41, and the lower end of the filter screen 42 is connected to a ring platform 43 mounted in the discharge pipe port 5.

[0035] When the slide frames 15 on both sides slide close to each other, the upper inclined block 37 can first fit and slide against the lower inclined block 44, and then slide against the upper end surface of the mounting frame 39, and at the same time drive the mounting frame 39 to slide downward along the second slide rod 38, and compress the third spring 40, thereby driving the filter screen 42 and the ring platform 43 connected by the connecting rod 41 to move downward and be sleeved in the discharge pipe port 5, ensuring that the red mud suspension can be filtered after the water quenching is completed, preventing the red mud suspension from seeping out from the filter screen 42 and the side edge of the discharge pipe port 5, and ensuring the comprehensiveness of the filtration; When it is necessary to flush the water quenching furnace 2 and some red mud residue filtered therein, the sliding frames 15 on both sides are driven away from each other, eliminating the interference between the upper inclined block 37, the lower inclined block 44 and the mounting frame 39. At this time, the mounting frame 39 will drive the filter screen 42 and the ring platform 43 to move upward under the action of the spring three 40, and open the discharge pipe 5, so as to facilitate the direct discharge of the flushing waste liquid, and the portable cleaning of the water quenching furnace 2 can effectively ensure the efficiency of the red mud water quenching.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
